half the length of the first joint of the flagellum." In the present 

 specimens the accessory appendage is about two-thirds the length 

 of the first joint of the flagellum, and bears a slender second joint, 

 tipped with several short spinules, which is not quite half the length 

 of the first joint. The first joint bears on its lower distal corner a 

 long slender spine, which reaches to the middle of the second joint 

 of the flagellum. The dactyl of the first and second peraeopods bears 

 a stout tooth on the inner margin near the hinge. The inner plates 

 of the maxillipeds are apparently shorter than those figured by Sars, 

 not reaching to the base of the first joint of the palp.
